Apple has just released iOS 5 beta 2, that brings forth a couple of interesting features, such as WiFi sync with iTunes, but only on the Mac. Other things worth mentioning are that starting with iOS 5.0 video content in apps and websites gets AirPlay support as default.
The issue of the Bluetooth connection to a Personal Hot Spot has been fixed and Internet connection for browsing is now possible. In the new beta, you get some issues, as usual, so remember to backup and test with care. Of course, this build is for developers, so you wouldn’t want to mess with it. You need iTunes 10.5 beta 2 and iOS 5 beta 2 in order to start the WiFi syncing.
You also get a new Apple boot logo animation and the notifications from the lockscreen have been retouched and given a larger size.
